How to scroll vertically by less than a full row in a WPF DataGrid?

In WPF DataGrid (SfDataGrid), vertical scrolling by default advances one full row at a time. This behavior can be customized to scroll by specific units by adjusting the vertical offset within the ScrollChanged event.

sfDataGrid.Loaded += OnLoaded;

private void OnLoaded(object sender, RoutedEventArgs e)
{
   this.sfDataGrid.GetVisualContainer().ScrollOwner.ScrollChanged += OnScrollChanged;          
}

private void OnScrollChanged(object sender, ScrollChangedEventArgs e)
{
   if (e.VerticalChange == 24)
    {
       if (e.VerticalChange > 0)
        {                    
            // Here customize based on your scenario
            double newOffset = e.VerticalOffset - 12;            
            this.sfDataGrid.GetVisualContainer().SetVerticalOffset(newOffset);
        }
    }
    if (e.VerticalChange == -24)
     {
        if (e.VerticalChange < 0)
         {
             // Here customize based on your scenario
             double newOffset = e.VerticalOffset + 12;              
           this.sfDataGrid.GetVisualContainer().SetVerticalOffset(newOffset);
          }
     }
 }
